This is the third spawn and the fry have been free swimming a few days before I noticed... currently culturing live brine shrimp for them and they are taking it eagerly. In another week I will alternate Hikari First Bites. The water bottle hatchery is working well and I syphon off the bottom. Great parents, the fry stray out of sight, mom and dad will round them up, eat them and spit the little guys back in the nest. Smart fish. The plan is to keep just a few and let nature take it's course.
